Obtaining Device's MAC Address

[gibbonsd]

I have been asked to find a way to obtain the device's MAC address.   I know in the Canvas Data Portal and the Page View's CSV file the Remote IP address is captured.  However, I am aware IP Addresses are shared and need the device's MAC Address.  I do not see if Canvas stores the device's MAC Address in the tables. 

Does anyone know if Canvas tracks device's MAC Address?

Canvas does not track MAC addresses, so you'd have to find those from another source.  There are also some significant technical restrictions on what you'll be able to get: if you're concerned about IP addresses being reassigned to other computers later, that means you'll have to do the IP->MAC lookup immediately in response to that computer's web request instead of doing the lookups afterward in a large batch; and at most, you can find them for computers on your local network, not across the Internet.
